§15.7 Continued Fractions

Notes:

See Andrews et al. (1999, pp. 94, 97–98, and Ex. 26 on p. 119),
Lorentzen and Waadeland (1992, §6.1), and
Berndt (1989, pp. 134–137).
These references contain several restrictions on the parameters a, b,
and c. This is because they use the function F⁡(a,b;c;z).
No restrictions are needed for F⁡(a,b;c;z).
